Samhyun Co., Ltd
Korean motion control specialist making 3-in-1 integrated motor-reducer-controller modules, smart actuators, and high-payload autonomous mobile robots.
Samhyun Co., Ltd. is a South Korean precision motion control and robotics company founded in 1988 and headquartered in Changwon, Gyeongsangnam-do. Listed on the KOSDAQ exchange (ticker: 437730), the company began as an automotive parts manufacturer and has evolved into a vertically integrated developer of motion control systems and industrial robot platforms.
Samhyun's core technological differentiation is its 3-in-1 Integrated Drive Module, which combines a motor, gear reducer, and controller into a single compact unit. This integration reduces overall volume by approximately 30% and weight by 20% compared to conventional three-separate-component configurations, while improving system efficiency and reducing bill-of-materials cost. Samhyun is recognized as the only company in South Korea capable of developing and manufacturing all three key technology components entirely in-house.
The company's product portfolio spans Physical AI Joint Motors, Smart Actuators, and Smart Power Units for robotic and mobility applications. In the autonomous mobile robot segment, Samhyun has developed HAMR (Heavy-duty Autonomous Mobile Robot), a next-generation industrial platform capable of high-speed operation up to 20 km/h, carrying loads between 3 and 10 tons, and navigating both indoor and outdoor environments using multi-sensor fusion. HAMR won the Excellent Product of the Year Award at ROBOTWORLD 2025.
The company has expanded into defense with the HOFLON unmanned ground vehicle platform, and into advanced air mobility (AAM). Samhyun strengthened its software capabilities through the acquisition of CASELAB, a robot software specialist, enabling tighter hardware-software integration. The company has established subsidiaries in India and China and is developing a path to enter the U.S. and European markets. Hyundai WIA's robotics division has engaged Samhyun as a strategic partner.
